HW2020: Prototype LHWZ-synergy-model
In the HW2020 project, a methodology for conceptual, partial-area-oriented, hydrological modeling is being created as an example for the catchment area of the Großer Röder up to the gauge Kleinraschütz. An integral part of the project is the synergetic use of aspects of the topological division of the area, the dam effects, data assimilation and state tracking, error correction, parameter estimation and the determination of the predictive uncertainty when using meteorological ensemble forecasts. The aim is a gauge-related flow forecast and the derivation of areal flood early warning products.
The chair of hydrology at the TU Dresden takes on the part of the model construction with Raven and the fine calibration of the model HydPy. In addition, strategies for data assimilation and error correction are designed and tested for the models.
In addition to the deterministic, hydrological models, a data-driven model for precipitation-discharge-modeling is set up for comparison. In particular, for low flow conditions, an advantage in terms of computing resources with high quality at the same time is to be expected. The hydrological models are set up in such a way that they can represent the topology scheme of the catchment area in a modular manner. This includes the designation of translation routes as well as the handling of dams.
